COAL AND ROCK DRILLING M ACHlNE.

SPECIFICATION forming part of Letters Patent No. 363,477, dated May 24,1887.

Application filed "December 23, 1886. Serial No. 22235-9. (No model.) H

To all whom it may concern:

Be it known that I, EDMUND MosER, a citizen'of the UnitedStates,residing at Pittsburg, in the county of Grawfordand State of Kansas,have invented a new and useful Improvement in Coal and Rock DrillingMachines, of which the following is a specification.

My invention relates to an improvement in coal and rock drillingmachines, to be used in mining and for drilling when sinking shafts;

and it consists in the peculiar construction and fied form of myinvention.

A represents a vertical post, which is provided at its upper end with athreaded socket, B, in which is located an extensionscrew, G, the upperend of which is pointed, as at D. An opening is made transversely in thescrew,

and through the said opening extends a crossbar or handle, E, which isadapted to slide freely in the opening, and is provided at itsextremities with enlarged heads. 'In the lower end of the post A is madeavertical socket, F, in which is located an extension-rod, G, the lowerend of which is broadened to form a foot, H, having thedownwardly-extending points or prongs I, which are adapted to enter theground at the lower side of the drift while the point D enters the upperside of the drift, and thus secures the post firmly in a verticalposition or at any desired angle therein. The clamping-screw K passesthrough a threaded opening that is made transversely in the lower end ofthe post and communicates with the socket F, the function of thisset-screw being to bear against the extensible rod G, so as to securethe latter at any desired adjustment in the post. It will be observedthat by providing the screw 0 at the upper end of the post the point Dmaybe extended or retracted, and thus the post is made extensible atboth ends, to adapt it to fit a drift or gallery of any diam eter.

' L represents a box, which is provided with a vertical opening, throughwhich the post A and through the same is made a transverse opening, U.

N represents a clamping-screw, which works in a threaded opening that ismade at right angles to the opening I and communicates with the same.

0 represents a block, which is provided with a rectangular transverseopening, 1?. From one side of the block projects an arm, R, having areduced extremity or spindle, R, which extends through the opening L",and is clamped therein by the screw N. From the outer side of the block0 projects a spindle, S, the outer end of which is screw-threaded.

T represents the longitudinal sleeve, which is rectangular incross-section and adapted to fit in the opening P. The said sleeve isprovided with a longitudinal threaded opening, through which extends ascrew-shaft, U, the ends of which are reduced and are made rectangularin cross-section, and thereby adaptit to fit a wrench or socket. Thissleeve T is secured in the opening in the block 0 by any desiredadjustment by means of a clamping screw, 0, with which the block isprovided.

V represents a miter gearwheel, which is splined or feathered on thescrewshaft U, to adapt the latter to flyvertically through themiter-wheel and cause thesaid shaft to rotate with the latter when thewheel is turned.

WV represents a beveled pinion,which is j ournaled on the spindle S, andis provided on its outer side with an annular sleeve or collar, \V. Thewheel WV meshes with the wheel V, and to the annular collar or sleevethereof is attached a crank-handle, X, by means of a clamp-screw, X. Anut, S, is screwed on the threaded outer end of the spindle S, toprevent the pinion WV and the crank-handle from becoming accidentallydetached from the said spindle. a

Y represents a curved or bent arm, which has one end bolted to the underside of the block O,and the other end bearing against the rear side ofthe hub of the gear-wheel V, so as to prevent the latter from becomingdisengaged from the pinion.

Z represents the ordinary drill-bit which is used for making theopenings in the vein or coal or in the rock, and is provided at its rearend with a socket, whereby it may be attached to one of the reduced endsofthe screwshaft.

The operation of my invention will be readily understood. By adjustingthe block L vertically on the post A. an opening may be drilled in thevein or coal or in the rock at any desired elevation, and by turning theblock in the arm L of the box the bit may be caused to work at anydesired angle. In order to rotate the bit and urge it forward throughthe rock or coal, it is only necessary for the operator to rotate thecrank in the direction indicated by the arrow in Fig. 1, so as to impartrotation to the pinion, and motion is conveyed therefrom to the wheel V,and through the latter to the screw-shaft and bit. As the screw-shaftpasses through the sleeve Tit will be noted that it is urged forwardthrough the same at each rotation a distance corresponding to the pitchof the screw-threads thereof.

7 In Fig. 6 I illustrate a modified form of my invention, in which Isimply employ a block that is attached to the box L in the mannerhereinbefore described, and dispense with the gearing to actuate thescrew-shaft, employing instead a crank-arm, A, which is adapted to fitone end of the screwshaft.

Having thus described my invention, I claim 1. In a drilling-machine,the combination of a post, a vertically-adjustable box fitted there on,a horizontallydisposed block pivotallysecured to the box, alongitudinallyadjustable sleeve passing transversely through the blockand at right angles to the bore of the box, and a threaded feed-shaftcarried by and working through said sleeve, substantially as specified.

2. In a drilling-machine, the combination of a post, a verticallyadjustable box, L, fitted thereon, and having an outwardly-projectedarm, L, provided with a transverse opening, a block, 0, having a spindleaffixed thereto and fitted in the transverseopening in the arm, abinding-screw working in the arm and bearing against the spindle to holdthe latter and the block to their adjusted positions, and a feed shaftworking in the block, substantially as described.

3. In a drilling-machine, the combination of a standard, a block, 0,carried thereby, afeedshaft extending through the block at right anglesto its length, the gear-wheel V, splined or feathered to the feed-shaft,a pinion, \V, journaled on an arm of the block and mesh ing with thewheel, and an arm, Y, at'fixed to the under side of the block and havingone end thereof bearing against the hub of the wheel V, to prevent thesame from partaking of the retrograde movement of the feed-shaft,substantially as described.

4. In a drilling-machine, the combination of a post, avertically-adjustable box fitted thereon, a block, 0, pivoted to the boXand having a transverse angular'opening, a non-rotatable sleeve, T,angularin cross-section, fitted in the eorrespondinglyshaped opening inthe block, and having a central threaded opening, a binding screwworking in the block and bearing against the sleeve to hold the same atany desired longitudinal adjustment, and a feed-shaft working in thethreaded opening of the sleeve, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signaturein presence of two witnesses.

EDMUND MOSER.
